Iinkcukacha zeMveliso
The scale on the double regulating valve hand wheel can help you accurately control the flow of the valve.
Engineered for precision flow control in HVAC water systems, this dual-regulation valve combines DZR bronze construction with advanced Venturi orifice technology. Its non-linear resistance characteristic ensures stable pressure signals while maintaining minimal system head loss (±2% accuracy).
Key specifications:
▸ Temperature range: -10°C to 130°C (continuous operation)
▸ Pressure rating: 25 bar @110°C / 20 bar @130°C
▸ Full-bore design maintains 95 %+ flow coefficient (Cv)
▸ Compatible with glycol mixtures (up to 25% concentration)
Certified for use in:
• Chilled water balancing
• District heating networks
• Hospital water systems (HTM 2045 compliant)
• Critical process cooling circuits
The calibrated dual-scale adjustment (0.5% resolution) enables repeatable flow measurement without requiring downstream straight pipe sections.
